Baker Hughes Incorporated (NYSE:BHI) announces the introduction of its DEEPFRAC™ deepwater multistage fracturing service, which can save operators hundreds of millions of dollars in offshore developments through unprecedented efficiency gains across the completion phase.

Using multiposition sleeves and patented flowback control technology, the service accelerates or eliminates certain steps of conventional multizone completion operations and enables rapid stimulation of 20+ stages. This translates into significantly greater reservoir contact, with an average OPEX savings of USD 30 to 40 million per well.

“Historically, operators who needed to stimulate their offshore wells were faced with complex completion operations that could take longer than a month and with costs approaching a hundred million dollars,” said Jim Sessions, Vice President, Completions at Baker Hughes. “By adapting some of the technologies and techniques that delivered game-changing efficiencies in unconventional land to an offshore service, we’ve enabled a new level of deepwater completion design flexibility and streamlined operations—all without compromising our commitment to safety and compliance.”

Typically, after a deepwater well has been drilled, the subsequent completion phase involves multiple, time-consuming steps. In contrast, the DEEPFRAC service eliminates casing and cementing operations and simplifies fluid logistics by using ball-activated, multiposition sleeves that can be installed in openhole wellbores containing drilling mud. And, unlike conventional offshore systems’ complicated tool running procedures and extensive mechanical manipulation requirements, no tool movement is needed during the DEEPFRAC service’s stimulation process. The sleeve’s ball activation enables continuous pumping from the first stage to the last, cutting the lower completion phase from weeks to days.

Conventional offshore stimulation systems are often limited to only five zones or ‘stages’ and these systems lack configuration flexibility that often results in uneven treatments and creates long sections of ‘dead space’ that cover up hundreds of feet of viable pay. The sleeves used in the DEEPFRAC service are modular and flexible, enabling placement of 20+ tightly-spaced stages across the pay zone to ensure more uniform treatments and to maximize reservoir contact.

After stimulation operations are complete, Baker Hughes IN-Tallic™ disintegrating frac balls allow production to flow without intervention. Patented Baker Hughes BeadScreen™ proppant flowback control technology built directly into the DEEPFRAC sleeve’s production ports provides increased reliability over conventional sand screens through higher burst/collapse ratings and improved erosion/plugging resistance, helping to ensure long-term, sand-free production.

On a recent job, the DEEPFRAC service saved an estimated 25 days rig time and USD 40 million on a first-ever 15-stage deepwater completion in the Gulf of Mexico’s Lower Tertiary.

The DEEPFRAC service is the latest example of Baker Hughes’ strategy to improve well efficiency, optimize production and increase ultimate recovery.
